In this case, for the electronic device 200 and the display screen assembly 100, an adhesive property between the second joining portion 22 of the connector 20 and the side wall 13 of the display screen 10 further restricts the delamination and crack of the display screen 10.

As illustrated in FIG. 9, in some embodiments, further, the third joining portion 23 of the connector 20 is joined to the bottom surface 12 of the display screen 10. In some embodiments, the third joining portion 23 is joined to the bottom surface 12 of the display screen 10 by means of adhering. In some embodiments, the third joining portion 23 is not limited to being coupled to the display screen 10 by means of adhering, and the third joining portion 23 can also be coupled to the bottom surface 12 of the display screen 10 by means of snapping, welding or the like.

As illustrated in FIG. 4, in some embodiments, the bracket 40 includes a side wall 42 extending upwards from an edge of the top portion 41, and the display screen assembly 100 further includes a decoration enclosure 70. The decoration enclosure 70 is arranged at a top of the side wall 42 of the bracket 40 and surrounds the cover plate 30 and the display screen 10. In some embodiments, the decoration enclosure 70 can be made of plastic, and the decoration enclosure 70 is joined with the bracket 40 by means of in-mold injection molding, in which the bracket 40 is prepared in advance. In other embodiments, the decoration enclosure 70 and the bracket 40 are integrally molded and produced to form an integral structure.

As illustrated in FIG. 10, in some embodiments, further, the second joining portion 22 of the connector 20 is joined to the side wall 42 of the bracket 40. In some embodiments, the second joining portion 22 is joined to the side wall 42 of the bracket 40 by means of adhering. In some embodiments, the second joining portion 22 is not limited to being coupled to the bracket 40 by means of adhering, and the second joining portion 22 can also be coupled to the side wall 42 of the bracket 40 by means of snapping, welding or the like. In this way, the connector 20 can be joined to multiple surfaces (the top surface 41 and the side wall 42) of the bracket 40, such that the connection between the connector 20 and the bracket 40 is stable.

Thus, the connection between the cover plate 30 and the bracket 40 can be stable by using the connector 20, the upward pull force exerted on the display screen 20 by the cover plate 30 can be further reduced, and the delamination and crack of the display screen 10 can be further avoided.

In the electronic device 200, the display screen assembly 100 and the method for assembling the display screen assembly according to embodiments of the present disclosure, the connector 20 is used to join the cover plate 30 with the bracket 40, such that when the electronic device 200 falls down and hence has a collision or shake, the cover plate 30 pulls the display screen 10 upwards due to the collision or shake, and the connector 20 applies a downward pull force to the cover plate 30 so as to reduce an upward pull force exerted on the display screen 10 by the cover plate 30, thus preventing the display screen 10 from delamination and crack. In addition, since the first joining portion 21, the second joining portion 22, the third joining portion 23 and the bracket 40 envelope the side wall 13 of the display screen 10 together, the delamination and crack of the display screen 10 are further restricted.

In some embodiments, an area where the first joining portion 21 of the connector 20 is adhered to the non-display area 15 of the display screen 10 is less than or equal to an area of the non-display area 15, i.e. the first joining portion 21 covers part or all of the non-display area 15. Thus, the first joining portion 21 can be prevented from shielding the display area 14 of the display screen 10, and the display screen 10 is ensured to have a large display area.

As illustrated in FIG. 16, in some embodiments, the first joining portion 21 of the connector 20 is joined to the top surface 11 of the display screen 10. In some embodiments, the first joining portion 21 is joined to the top surface 11 of the display screen 10 by means of adhering. In some embodiments, the first joining portion 21 is not limited to being coupled to the display screen 10 by means of adhering, and the first joining portion 21 can also be coupled to the top surface 11 of the display screen 10 by means of snapping, welding or the like.

As illustrated in FIG. 17, in some embodiments, the second joining portion 22 of the connector 20 is joined to the side wall 13 of the display screen 10. In some embodiments, the second joining portion 22 is joined to the side wall 13 of the display screen 10 by means of adhering. In some embodiments, the second joining portion 22 is not limited to being coupled to the display screen 10 by means of adhering, and the second joining portion 22 can also be coupled to the side wall 13 of the display screen 10 by means of snapping, welding or the like. In this case, for the electronic device 200 and the display screen assembly 100, an adhesive property between the second joining portion 22 of the connector 20 and the side wall 13 of the display screen 10 further restricts the delamination and crack of the display screen 10.

As illustrated in FIG. 12, in some embodiments, the bracket 40 includes a side wall 42 extending upwards from an edge of the top portion 41, and the display screen assembly 100 further includes a decoration enclosure 70. The decoration enclosure 70 is arranged at a top of the side wall 42 of the bracket 40 and surrounds the cover plate 30 and the display screen 10. In some embodiments, the decoration enclosure 70 can be made of plastic, and the decoration enclosure 70 is joined with the bracket 40 by means of in-mold injection molding, in which the bracket 40 is prepared in advance. In other embodiments, the decoration enclosure 70 and the bracket 40 can be integrally molded and produced to form an integral structure.

As illustrated in FIG. 18, in some embodiments, the second joining portion 22 of the connector 20 is joined to the side wall 42 of the bracket 40. In some embodiments, the second joining portion 22 is joined to the side wall 42 of the bracket 40 by means of adhering. In some embodiments, the second joining portion 22 is not limited to being coupled to the bracket 40 by means of adhering, and the second joining portion 22 can also be coupled to the side wall 42 of the bracket 40 by means of snapping, welding or the like. Thus, the connector 20 can be joined to multiple surfaces (the top surface 41 and the side wall 42) of the bracket 40, such that the connection between the connector 20 and the bracket 40 is stable. Thus, the connection between the cover plate 30 and the bracket 40 can be stable by using the connector 20, the upward pull force exerted on the display screen 20 by the cover plate 30 can be further reduced, and the delamination and crack of the display screen 10 can be further avoided.
